UNITED STATES PATENT OFFICE GAS GENERATOR Gustav Steiner, Ludwigshafen on the Rhine, Germany, assignorV to Wilhelm Dtzmann, Neustadt-on- `bhe-Haardt, Germany Application July 3, 1936, Serial No. 88,911 In Germany July 4, 1935 Claims. (Cl. f8-144) This invention relates to a method and deoperative and also serving for discharging oil vice for converting liquid, particularly difiicultly which has accumulated as liquid in the coil when volatile, fuels into a gaseous state so as to render the device is idle. In the mixing device I the them suitable for operating internal combustion homogenized fuel mixture is mixed withthe final 5 engines. amount of air and thence passes into the suction 5 The method according to the invention conconnection of the engine. sists in gradually adding water vapor with air The device functions as follows: and fresh air to the diilicultly volatile fuels pre- For starting the engine is actuated by means viously subjected to atomization and the impact of the gasoline lcarburetor 24. When the engine 1u with heated walls and in compensating at least has been lidling for about ve minutes or the 10 after each addition the drop in temperature vehicle has run 1 km., the gasoline supply can caused thereby by a supplementary supply of be stopped and the engine operated with diniheat. This gradual mixing of the fuel concultly volatile fuel. If the crude oil valve is acstituents with air insures a remarkably uniform tuated by the usual foot levers, the crude oil first l5 and economical distribution of the particles of enters the superheating jacket or hot bulb I 0 15 fuel in the mixture. The application of the through a calibrated nozzle and then through the method requires of course considerable heat guide pipe II the mixing member I2 into which which, according to the invention, is supplied by the air channel I3 opens. The channel I3 is in passing additional oxygen or air tothe exhaust communication with a device 5 comprising a gases flowing around the spaces wherein the lower part filled with water or another suitable 20 mixture is homogenized and thus causing the unliquid into which the wick I4 extends which leads burned constituents still contained in the exhaust to the upper part of the device 5. The upper gases to be burnt. part is perforated like a sieve and provided with The device for carrying' out this method coma connection I5. u prises a plurality of spaces wherein the diffcultly When the oil valve is actuated the flap I6 opens g5 volatile and atomized fuel coming from a nozzle and the suction effect of the engine continues is heated, split up and mixed with water vapor, th'rough the coil 3, so thatair is drawn in through and a coil to which additional air is supplied at the bores I`I shown in Fig. 1, enriched with water one or more places. The spaces mentioned are vapor and drawn into the mixing space I2. In surrounded by the exhaust gases and heated. At the meantime, the crude oil has been physically the end of the coil a mixing device is provided, disintegrated by passing the hot bulb I0 and enin which the homogenized gas mixture developing ters into reaction with the water particles conin the coil is supplied with air to the required tained `in the air current, whereby the formation extent. The exhaust piping contains nozzles or of a permanent gas is initiated. The heat lost u other means through which air can flow in. by the addition of the mixture of air and water By way of example, the invention ls illustrated vapor is supplied again t0 the developing eas in the accompanying drawing, in which Figure while it flows through the inner coil. After the 1 is a section of the device attached to an engine inner coil has been passed a small amount of air and Fig. 2 a detail view on an enlarged scale of in superheated form is supplied for rapid conthe mixing nozzle. version which is effected in the outer coil. The o Referring to the drawing, 2 is the exhaust pipcoil I8 acts as air heater and also prevents the ingof the engine, which .contains in a relatively coil 3, during stopping of the engine, from filling enlarged extension 2 the parts required for prowith oil, possibly owing to a leak in the oil valve, ducing the fuel mixture, i. e.. a superheating which would have disastrous consequences when space I0, a mixing space I2 and a connecting the engine is started. 5 coil 3 surrounded on all sides by the hot exhaust The gas formed then passes to the mixing gases. The diflcultly volatile fuel to be conmember I provided on its front side with the air verted is supplied through the nozzle Ii. 'Ihe admission bores I9 normally shutoff by the spring mixing space I2 is in communication with a deplate 20 in the absence of engine suction. 50 vice 5 for enriching the moisture content of the The inside further contains the air funnel 2| 50 primary air in such manner that the air drawn adjustable from without and the cone 22 which in through the openings I'I is forced to pass along regulates the gas supply and can also be adjusted the moist wick I4. At the lower end of the coil from the outside. The cone 22 as well as the 3 a second coil I8. also surrounded by exhaust air funnel 2l are connected through the wall of u gases, is provided for supplying fresh air when the mixing device `I by bolts movable in slots in 55 the wall to permit adjustment, and fixed ln adjusted position by thumb nuts.

'This device serves for insuring some movement of the gas and more intensive whirling with the air that follows. Heating of the spaces wherein the fuel mixture isehomogenized is eifected by supplying the exhaust gases coming out of the cylinder I withoxygen, for instance in the f orm of atmospheric air, and burning it together with the unburned constituents of the exhaust gases. This is brought about by means of a nozzle 23 lnserted between the exhaust flange and the cylinder block and made of heatand corrosion-resisting material and by providing the exhaust pipe 2 on its circumference with holes 25 which permit the supply of at least 20% air to the exhaust iiame.

Owing to the suction effect produced by the rapidly emerging waste gases, the flame is automatically enriched with air, regenerated and si` multaneously consumes all carbon monoxide andv chamber, means for admitting the fuel to the chamber for volatilizing, a mixing chamber, means for admitting the volatilized fuel to the mixing chamber, an air moistening device, means for admitting moistened air from the air molstening chamber to the mixing chamber forv mixing with the volatilized fuel, means forV directing the mixture through altortuous path under the l suction of the engine, means for admitting supplementary air to the mixture at a predetermined point in this path, and means for subjecting the volatilizingchamber, mixing chamber and tortu ouspath of the mixture to the continuous action of heat.
